BEIRUT (AP) -- The latest on the conflict in Syria, where a fragile cease-fire has entered its fifth day. (all times local):
Activists say Syrian government forces have killed five civilians in the latest alleged violations of a U.S. and Russian-brokered cease-fire.
The Britain-based Syrian Observatory for Human Rights says a woman and child were killed Saturday in Talbiseh, in the central Homs province. It says two men were killed outside Damascus and a child was killed in Aleppo province.
The Syrian Civil Defense group in Homs says government artillery caused the deaths in Talbiseh. A video of the rescue mission shows bodies strewn across the ground.
Syria's state news agency SANA says insurgents have violated the cease-fire 12 times in the last 12 hours.
The fragile truce has largely held since it went into effect Monday, despite alleged violations on both sides.
Russian Foreign Minister Sergey Lavrov and U.S. Secretary of State John Kerry have spoken by telephone about the fragile cease-fire in Syria and efforts to deliver aid to the northern city of Aleppo.
The Russian Foreign Ministry says Lavrov told Kerry that Russia has coordinated the aid delivery with Syrian government forces and called on Washington to exercise similar influence with Syrian rebels.
Lavrov noted the "refusal by an array of illegal armed groups to join the cease-fire" and Washington's obligation to "separate units of the moderate opposition from terrorist groupings."
The cease-fire has largely held since it went into effect on Monday, bringing calm to much of the country despite dozens of alleged violations on both sides.
Israel says its Iron Dome rocket defense system has intercepted a projectile fired from inside Syria into the Israeli-controlled part of the Golan Heights.
The military says the projectile was intercepted Saturday, without elaborating. No injuries or damage were reported.
Iron Dome protects against short-range rockets, and intercepted hundreds of projectiles fired by Palestinians militants during the 2014 Gaza war. Israeli media is reporting that the system intercepted a mortar round on Saturday, and that it's the first time Iron Dome has been successfully used in the north.
Israel has largely remained on the sidelines of the Syrian war but has carried out reprisals on Syrian positions when errant fire previously landed in Israel.
Russia's military says Syrian rebels have violated a cease-fire 55 times over the past day, including with strikes on military and civilian targets in the divided northern city of Aleppo.
The Interfax news agency quoted Col. Sergei Kopytsin as saying Saturday that mortar fire and improvised rockets struck Aleppo 26 times. Russian news agencies cited another official, Lt. Gen. Vladimir Savchenko, as saying there had been 55 violations throughout the country.
A tense cease-fire brokered by Moscow and Washington went into effect on Monday. The truce has largely held, despite dozens of alleged violations by both sides.
The cease-fire was supposed to pave the way for aid shipments into besieged rebel-held areas of Aleppo, but convoys have yet to enter.
Russian President Vladimir Putin is expressing frustration at Washington's refusal to publish the Syrian cease-fire deal reached with Russia, but says Moscow won't unilaterally release it.
"I don't really understand why we have to keep such an agreement closed," Putin was quoted as saying Saturday during a trip to Kyrgyzstan.
He suggested Washington's resistance stems from a hope to retain the combat potential of forces fighting the Syrian government.
"This comes from the problems the U.S. is facing on the Syrian track --- they still cannot separate the so-called healthy part of the opposition from the half-criminal and terrorist elements," he said. "In my opinion, this comes from the desire to keep the combat potential in fighting the legitimate government of Bashar Assad. But this is a very dangerous route."
